Abstract: 441,489. Printing-machines. QUICK, C. G., BENNISON, W. E., and ALEXANDER, D. A. H., 109, Borough Road, London. July 17, 1934, No. 20937. [Class 100 (ii)] Rotary-machines ; inking-apparatus.-In a rotary intaglio printing-machine having two doctor blade mechanisms arranged to be moved selectively into operative relationship with the printing-cylinder, the cylinder is provided with bearings which permit the cylinder to be withdrawn laterally therefrom and means are provided for moving one or the other of the doctor blade mechanisms clear of the cylinder in its translational movement. As shown, the cylinder 1 is mounted in open bearings 13 rotatable in blocks 14 so that the cylinder can be rolled laterally therefrom. The bearings are formed with teeth 24 gearing with vertical slidable racks 25 operated by pinions 28, worm wheel 30, worm 31 and hand wheel 33. Two doctor blade mechanisms 2, 3 which may be of the construction described in Specification 441,487, are provided and the mechanism 3, on the side toward which the cylinder moves in its movement from the bearings, is adapted to be lowered out of the path of the cylinder. For this purpose, the base 15 on which the mechanism is mounted, is vertically movable in guides on the frame and is raised and lowered by screws 17 connected by bevel gearing 18 to a cross-shaft 19 operable by chain and sprocket gear 20, 21, 22 and handle 23. Specification 441,488 also is referred to.

Abstract: 1428465 Maleinized esters DULUX AUSTRALIA Ltd 3 May 1973 [9 May 1972] 21012/73 Heading C2C A composition suitable for use as a filmformer in paint, comprises an ester of a monocarboxylic acid and di- or tripentaerythritol in which a portion of the ester moieties is reacted with maleic anhydride (2-20% of combined anhydride) and the anhydride moiety is esterified with a monohydroxy compound (C, H, and O and maximum M.W. 150) to give a succinyl acid half ester structure. Linseed, tung, fish, safflower, soya and sunflower oil fatty acids and tall oil fatty acids or mixtures thereof may be used. The hydroxy compounds may be saturated or unsaturated alcohols or hydroxy alkyl methacrylates or acrylates. The esters when catalysed e.g. with lead, cobalt, manganese or calcium naphthenate, dry in air to form hard, tough films, and the compositions may be pigmented and solvents and other drying oils added. Examples describe the preparation of esters from dipentaerythritol and safflower, soya, sunflower, and tall oil fatty acids, which are maleinized and reacted with hydroxyethyl methacrylate, and benzyl, allyl, butyl, alcohols. Tripentaerythritol based esters are also illustrated. Liquid paint compositions may be prepared by the addition of driers, anti-skinning agents and titanium dioxide.

Abstract: 1286916 Line couplers on automatic rail vehicle couplings MINISTERIUM FUR VERKEHERSWESEN 1 May 1970 21047/70 Heading B7T An automatic central buffer coupling for rail vehicles has mounted thereon a service line coupler 2 which during coupling of the buffer coupling with a counter coupling is moved forward into its coupling position by a lever 1, but wherein initial movement of the lever 1 only moves away a cover flap 5 from in front of the live coupler until lost motion 8 is taken up and the line coupler is actuated. The connection between lever 1 and the cover flap is by a lever 11 pivoted to lever 1 and having a pin and slot engagement with an angled lever 5a on which the flap is mounted. Engaging pins 6, 7 lock the line coupler in its rearward position until a coupling operation takes place, and a spring element extending between the lever 1 and the line coupling biases the latter rearwardly.

Title: Improvements in or relating to digital to analog converters
Inventor: WARD RICHARD
IPC: F15C1/00
Filed: 1969-04-25
Abstract: 1279419 Fluid digital to analog converters; counters WM PARK & CO FORGEMASTERS Ltd 20 April 1970 [25 April 1969] 21184/69 Headings G4D and G4P The output of a fluidic binary counter is converted to a torque proportional to the count. In one embodiment an assembly of cylinders 12 containing pistons 13 is secured to shaft 15, the torque developed by the assembly being balanced by spring 18. The fluid outputs of the counter are applied to respective cylinders to displace the pistons by an amount proportional to the binary weight of the respective bit. The resultant change in torque causes shaft 15 to rotate through a small angle and to drive a drum 17 through step-up gearing. Drum 17 carries numbers on its periphery to indicate the count. Springs 14 return the pistons when the counter output ceases. If no springs 14 are provided the pistons are reset by fluid pressure in pipe 19. In a second embodiment, Fig. 2 (not shown), no pistons are used. Each cylinder is divided in two by a circular apertured wall (23), the counter output causing fluid to be displaced from one side of the wall to the other to alter the torque applied to shaft 15. The assembly of cylinders may lie in a vertical plane, Fig. 3 (not shown), and instead of a drum display the torque may be determined via a force transducer.

Title: Improvements in and relating to the production of valuable products from heavy liquid hydrocarbons
Inventor: SAWYER EDWARD WILLIAM
IPC: C07C11/02
Filed: 1953-07-30
Abstract: Ethylene and aromatic hydrocarbons, e.g. benzene, xylene, naphthalene, are obtained relatively free from aliphatic and aliphatic substituted aromatic hydrocarbons by passing heavy liquid hydrocarbons, e.g. low and medium temperature tars, preferably freed from phenols on to a moving bed of particulate inert material where they are heated to temperatures of over 700 DEG  C. in presence of a carrier gas containing at least 30 per cent free hydrogen.  The moving bed may be a non-fluidized bed moving under gravity and consisting of coke, ceramic and like inert particles or it may be an ascending or descending fluidized bed; it may be heated to the required temperature by combustion of the coke deposited thereon. Vertical retort tar containing 3 per cent naphthalene and 8 per cent phenols was injected into a fluidized coke bed maintained at 810 DEG C. in presence of hydrogen.  The tar was fed at 880 gs. per hour and the hydrogen at 700 litres per hour.  The coke particles leaving the base of the reactor were lifted by a stream of air through a 1 1/2 inch combustion tube to a cyclone above the reactor from which coke was returned to the reactor.  The following percentages by weight of tar were recovered from the products: 6 per cent benzene, 6 per cent toluene, 1 per cent C8 aromatics, 4.5 per cent naphthalene, 9 per cent methane, 3.5 per cent ethylene, 1 per cent ethane.

Spray carburettors.-In a carburettor, strong suction is produced at the jet by using three Venturi tubes 12, 17, 16 one within the other, the jet orifices being contained in the smallest. As shown, for a vertically arranged mixing chamber the jet consists of a number of orifices leading from an annular chamber 15 connected by a pipe 14 to a well formed between a perforated tube 6 and the casing. The tube is connected to the atmosphere through the pipe 23, and the well is fed with fuel through two restricted orifices 10, 11 communicating with a fuel pipe 2, one or both of these orifices being submerged. The tube 6 may have on its outside a collar at 22 so that the lower orifice 11 supplies a constant quantity of fuel, the upper one only being influenced by the varying suction. The slow running outlet 9 is fed from a pipe 7 inside the tube 6, air for forming the mixture being admitted past the valve 21.
